Parker 164CA-5 Brass Compression Tube Union 1200 Psi

Product Description

The PARKER 164CA-5 is a brass compression tube union designed to join two tubing runs using compression fittings on all three connection points. This union provides a leak-resistant, tool-free connection suitable for gas, fluid, and pneumatic distribution systems in HVAC, plumbing, and instrumentation applications. Constructed from brass, it handles a maximum working pressure of 1200 psi and an operating temperature range of -65 degrees F to 250 degrees F, making it appropriate for a wide range of service conditions. Licensed plumbers, HVAC technicians, and instrumentation mechanics are the primary installers of this fitting type.

This union is suited for residential and light commercial installations where tubing runs must be joined or extended without soldering or flaring. The all-compression design allows connection directly to compatible tubing in confined or field-service environments where torch work is impractical. Typical applications include refrigerant-grade copper tubing connections, potable water distribution, and pneumatic control lines. The three-port compression configuration accommodates in-line tube joining with a single fitting body.

Key Features

• All-brass construction for corrosion resistance in plumbing, HVAC, and fluid system service
• Compression x Compression x Compression end connections — no soldering or flaring required
• Maximum working pressure of 1200 psi suitable for high-pressure fluid and gas lines
• Wide temperature range: -65 degrees F to 250 degrees F
• Compact union body for in-line tube joining in tight installations

Compatibility

Designed as an OEM-style replacement or new-installation compression union for brass-compatible tubing systems in HVAC, plumbing, and pneumatic applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable IPC or IFGC guidelines. Shut off the fluid or gas supply and relieve system pressure before removing or installing any compression fitting. Ensure tubing ends are cut square, deburred, and fully seated before tightening compression nuts. Do not overtighten — compression fittings achieve a seal through controlled nut torque; follow the fitting manufacturer's general guidance for hand-tight plus turn increments appropriate to the tubing material.
